Specification of Letters Patent; Patented B131. 14, 1922 Application filed December 23, 1920.' VrSerial No. 432,658. A

To all wim/n it mag/'concern I Beit known that I, EDWARD M.A Mo- NAMARA, a citizen of the United lStates of America, and a resident of Chicago, 1n the county of Cook, State of Illinois, have y1nvented certain new and useful Improvements in Mop Holders and VVringers, of which the following is a specification.

This invention relates to that' class of household mops in which the structure 1s the-mopping material in a rapid andcon'-V venient manner,and the ypresent improve-l ment has for its 0bjects: a

To provide a structural formation and association of the carrying frame and the mop carryingl roller, whereby an effective wringing of the mop material is attained.

To provide a' formation and combination To'prolvide a structural formation of the mop carrying drum whereby the fluid removed in a wringing operation is directedv outwardly awayfrom and clear'of the mop material, all as will hereinafter more fully appear.

In :theY accompanying drawing I Fig. 1, is a sectional elevation illustrating the preferred construction of the present;

invention.

" Fig. 2, is a detail end elevation, with parts in section on line 2 2 Figyl, and showing the 'parts in a wringing position.

Fig. 3, is la similar end elevation showing theparts in a position to permit a detachmentI of the drum Vor roller. y

Fig.` 4, 'is 'a detail section von line4-4 Fi pl. I

Fig. 5, is an elevation, with parts in sec'- tion "of 'a modified form'of thefinven'tion F ig.' 6, is yan end view of the carrying"V roller o'f the same;

Like reference numerals indicate likeparts in the several views.

Referring to the drawing, "l designates the Yframe of the implement formed'with a main transverse barA or rail the underside of which is preferably of the arch form shown, with a central` socket 2 for the usual mop handle or stick, a transverse baror member atl one 'end ofsaid socket, and depending journal Aformation illustrated in Figs. 5 and 6, or

adapted to effect a wringing operation of `bymeans of channel or trough shaped bars 'ceive the foldv of the mop material 7 at the point of operative connection with the drum 4 and in orderl that said fold maybe in proper relation to the drum` to permit an even rolling of thev mop material around the dru'm` in 4a manipulation ofy parts to effect'a wringing of the said mop material;

` The rmeans for detachably connecting the drum or roller 4 to the ears 3 of the supporting frame, aswell as for effecting a manual rotation of the drum comprises a member 'having a structural formation `as follows Svdesignates a rod or rail, which when in place, hasrparallel relation to the periphery of the drum 4 and the longitudinal recess 6 thereofand adapted to receive the attaching fold of the mop material 7 to hold the same in proper operative connection with the drum. v

9 designates right angle extensions at the respect-ive ends of the rod 8 aforesaid, and adapted to engage in the end channels 5 of the'drum 4 to attain an operative connection between the parts capable of manual disassociation -when required.

lO designates aligned journal portions extendingv at right angles to the extensions 9 aforesaid. and adapted for revoluble engagement in journals provided therefor on the freeends of the prongs 34 of the supporting frame.` Y

ll designates a lever extending from the outer end of one of the journal portions 10 p' aforesaid, and provided at its free end with gagement with a latch member 13 pivotally mounted on the socket portion 2 ofthe supporting frame, so that when the parts are in a latched condition the lever portion112`will be held from revoluble movement.

In the present construction the wringing of the mop material 7 is effected by a revolution of the drum 4 to attain a windingup of the mop materialuponits periphery, and,

to carry said material through the restricted space between the periphery of the drum and under edge of the main transverse bar of the supporting frame 1 to attain aneffective compressive o-r squeezing action upon the mop material at such point. In the preferred construction shown in Fig. 2, the for'- wa'rdedge 1 of the transverse bar of the frame 1, is 'arranged in closer relation to the` peripheryof the drum 4 than the rearedge l of``said transverse bar, so that in a wringing movement of the drum or roller 4 the edge 1 will bear upon the passing mop material and eXert a squeezing or squeegee action upon the same to very effectively re- -move the liquid therefrom. Witha turning movement of the drum V4 in a reverse direction, the edge 1 acts to'hold the mop material'so that the lportion of said material between its' attaching fold and the edge 1 will bank upl and become loosened for effective moppingpurposes in confined places.

14 designates a series of orifices formed in the circularwall of the tubular type of drum or roller, and with a View to prevent the flow of the Vexpressed Huid back into the squeezed portionof the mop materialsaid orifices areformedwith inturned lips or fiangesto constitute damsl against such returnan'd cause 'the liquid ,to lflow out or escape at the endsof' the drum. i

Irrthe modified construction shown in Fig, 5, the connecting means .above described 1s.

journalleddirectly in the endears of the framel and under lordinary Vconditions affordsv satisfactory results inl actual use. A yielding lconnection such as shown in Fig. 1 has `been found more desirable however, and comprises an arrangement of parts as 'follows :-y

" l 15I designates a pair of bars arranged kfor sliding movement in, the' end ears 3 of the frame l, and provided with journaleyes at their lower ends affording bearings for the aligned journal portions 10 of the connecting means above described. j

16 designates a transversely arranged spring-'attached'to therframe 1 with its respective ends engaging Vthe upper ends of the "bars '15 aforesaid, and adapted to veirert an upward stress upon the same to resiliently force and holdthe drum in the direction of thecoacting transverse bar of the supporting frame 1.

-said socket and depending journal ears at the ends 4of said bar, a drum .1-evolubly. mounted in said ears in operative relation' to said transverse bar so that the bar will have direct squeezing action upon the mop material as thefdrum vis rotated, means for connectingV the mop .materiahto the drum, and fmeans forxiinparting rotation to` the f dru 2.- In a combined mop Vand ivringer, the combination of afi-ame having a transverse bar and end prongs,1a tubular drumV revolubly associatedy vwith said'nl prongsfin operative relation toV said' transverse barf and khaving inwardly flanged `orifices inl its circular wall, meansV for `connecting the mopl material to the' periphery-ofsaid drum, and' Y manual means lfor imparting rotation to said drum..
